碩士 === 國立臺北科技大學 === 電機工程系所 === 94 === As a result of the influences from energy crisis and escalating environmental protection awareness in the recent years, developing renewable energy has clearly become the popular trend. Among the many renewable resources, wind power generation, after on-going research and development and as well as the technology enhancement, has advanced to commercial mass-production. Therefore, there are more and more wind power generators being installed. To prevent potential disturbing occurrences from happening when joining up wind power generators in parallel with the main electricity supply system, current situation needs to be emphasized and must undertake further study in terms of how voltages will change after joining in parallel, how it will impact the qualify of life for the users, and how to protect the safety and coordinate different personnel in the operation. The Penghu region is rich in wind power resources although the local power system is small in scale as well as is an independent system, thus it is relatively fragile where the quality of energy is easily interfered by the instability of the wind. The existing power system in the region is the subject of this study where the impact and influences on the system created by the energies generated by the 8 wind power generators, are analyzed with the loading management at off peak conditions. The research attempts to understand the characteristics of the dynamic behaviors of the system using the concept of energy transfer through bond graph theory analysis, and in conjunction with the procedure conversion of the Simulink software modules. On analyzing dynamic behavior of the system through energy concept, system condition and functions are reflected immediately when data such as generation volume and circuit loading of the system are integrated, providing maintenance teams the basis for improvement and compensation on the weaknesses of the system such as voltage drops or losses. This study serves as a reference for a reasonable ratio between the capacity of wind generator facilities and the system loading, and provides a new direction for the research in power system analysis.
